Milking the proverbial withered tit of a dead game. The Wig's make a lot of money nearly 43,500 euro's a month at this rate, if you added purchased gold packs it might as well calculate to 50,000 + euro's a month. Meanwhile free-to-players are dying on +10/+20 energy refill and logging in one or two sessions a day.

I think 50,000 euro isn't something impressive. According to their LinkedIn page, they have 51-200 employees. They are also working on other games like Age of Lords but I don't think they are profitable like eRepublik. edit: Or maybe they are: Age of Lords is rated 5 stars from 38k people and World at War from 25k people.
